WHMCS changing database - php

Question

I'm still trying to understand why in WHMCS on the same MySQL database if I try to connect to a different db, he still tries to search a table in his default database.
Example: I'm trying to connect to the table "test" in "admin_test" so he needs to search for "admin_test.test", but instead he gives me the error:
VPN Database Query Error: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'admin_billing.test' doesn't exist (SQL: insert into test (user_id) values (fdffddfg))
So I think he doesn't want to change db, I tried to write this module based on the freeradius module, as it works fine and has his own db on the same localhost mysql.. I don't know how to fix this as of now.
function rscmodule_DatabaseInsert()
{
try {
$vpnsql = rscmodule_DatabaseConnect();
if (is_string($vpnsql)) {
return $vpnsql; // Error condition
}
Capsule::connection()->transaction(
function ($vpnsql)
{
/** #var \Illuminate\Database\Connection $connectionManager */
$vpnsql->table('test')->insert(
[
'user_id' => 'fdffddfg',
]
);
}
);
} catch (\Exception $e) {
return "VPN Database Query Error: " . $e->getMessage();
}
return "success";
}
function rscmodule_DatabaseConnect()
{
$pdo = null;
try {
$pdo = Capsule::getInstance()->getConnection('rscmodule');
} catch (\Exception $e) {
$config = array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'admin_test',
'username' => 'admin_test',
'password' => '*****',
'charset' => 'utf8',
);
try {
Capsule::getInstance()->addConnection(
$config,
'rscmodule'
);
$pdo = Capsule::getInstance()->getConnection('rscmodule');
} catch (\Exception $e) {
return "Unable to connect to rscmodule Database. "
. "Please check rscmodule server configuration. "
. $e->getMessage();
}
}
if (is_object($pdo)) {
if (method_exists($pdo, 'query')) {
$ret = $pdo->query();
} else {
$processor = $pdo->getPostProcessor();
$ret = new \Illuminate\Database\Query\Builder($pdo, $pdo->getQueryGrammar(), $processor);
}
} else {
$ret = $pdo;
}
return $ret;
}

Well turns out WHMCS doesn't want other DBs inside the same connection IP, so we created a VM on a new IP and on that the connection works properly.
